My BF is supposed to do one of these and has been putting it off because he thinks that it will be a giant waste of his time, and I can't help but secretly agree, even though I have been encouraging him to follow his Doctor's orders. He is so weird about sleeping, all these little "rules" he has to follow. I don't think there is anyway he could sleep in a manner like that which has been described. Also, if it is above 65 degrees and there are less than four pillows for him to use, he isn't sleeping... And sleep on his back? Forget it!
